Udon Noodle Soup with Crisp Vegetables

In this Japanese-style soup, udon noodles in a hot broth are topped with crisp raw vegetables, making for an offbeat and pleasing presentation. It can be made minutes before you wish to serve it. The traditional way to eat this is to “slurp” the noodles with the help of chopsticks, then finish off the remaining soup with a spoon. Photos by Hannah Kaminsky.
